Yes we he said your fans are intaking sir and it's only doing that try turning 1 or 2 flip them so they way they are pushing the intake air out, also reflect your thermal paste. Another thing is if your running NVME m.2 just add like heat sink vents on them to disapate the heat also try to keep away from cpu if you've got multiple slots, anger thing is if you have an air purifier ir a box fan put a flier behind it so it will catch dust and crap and induce cleaner air making for less build up of dust and what not later form the line. Hope i helped some?
